Isolation And Characterisation Of A Pax Group Iii Gene From The Freshwater Crayfish Cherax Destructor: Implications For The Evolution Of Muscle Regeneration, Robert B. White
Theses : Honours
Pax genes encode transcription factors that are highly evolutionarily conserved and are vital for animal development. Vertebrate Pax group III genes Pax3 and Pax7 are required for proper development of muscular and central nervous systems. In their roles in muscular systems, Pax3 and Pax7 specify myoblasts (muscle progenitor cells). Pax3 is predominantly involved in embryonic myogenesis and specifies embryonic myoblasts. In contrast, Pax7 specifies adult myoblasts (muscle satellite cells), and has been demonstrated to be vital for adult muscle regeneration. Recent evidence also implicates a role for Pax7 in the conversion of certain stem cells to the myogenic lineage. The …
